KDA 1.1-050-300-W1-220

The KDA 1.1-050-300-W1-220, Bosch Rexroth Indramat’s precision spindle regulator is part of the KDA Spindle Drives series designed for high-stiffness, high-precision applications. This main spindle drive provides dynamic speed control across a wide range and delivers consistent performance under continuous load. The compact module incorporates advanced positioning features and optimized thermal management. Engineers benefit from factory-assigned parameter defaults that accelerate commissioning and reduce setup time.

The drive accepts a DC Bus Voltage of 300 V and a Rated Current of 50 A, ensuring robust torque delivery for demanding spindle tasks. Cooling is achieved by a Forced Cooled by Heatsink Blower system operating on AC Supply Source for Heatsink Blower at 220 VAC, which maintains stable junction temperatures during extended operation. All auxiliary channels, including Aux. Encoder Input and Aux. Interface, are Factory Assigned to streamline integration with machine controllers. The built-in Speed Command Value and the native Series configuration allow seamless networking within the machine’s motion control topology.

Rugged design and forced-air cooling boost reliability in high-duty-cycle environments, minimizing thermal drift and downtime. The drive’s compact footprint and factory-loaded encoder settings simplify retrofits and new installations alike. Ideal for precision milling and turning centers, the KDA 1.1-050-300-W1-220 delivers consistent accuracy, repeatability, and rapid response for next-generation machine tools.
